did any 3/4 front axles(8 lug dana44 or 10bolt) come with factory 4.56
maybe some of the military axles have 4.56 in them not sure though
K20'S from 73 to 80 had 4:56 gears available on six and eight cylinder trucks (d44 to 77 10 bolt to 80).K10's were available 81-83. Nearly all K30's were D60 fronts. This is from a chart I downloaded, however due to assembly line missteps anything could of been installed into a model not normally equipped.
